, REFRIGERATOR.

Application filed November 29, 1924. Serial N0. 752,962.

To all whom it may concern:

Be it known that I, FREDD. PRATT, a citizen of the United States, residing at Green Bay, in the county of Brown and State of \Visconsin, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to refrigerators, more particularly of the class of small portable refrigerator"devices capable of being supported on the running board or other part of a motor driven vehicle, and has for one of its objects to simplify the construc-' tion and increase the utility and convenience of devices of this character.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention Fig. 1 is a longitudinal section, and 1 Fig. 2 is a transverse section, of the improved device.

Fig. 3 is a plan view 3--3 of Fig. 1 a

The improved device is designed more particularly to be supported upon automobiles and the like for the use of tourist and camping parties, and is shown for illustration arranged upon a section of a r'unning board indicated at. 10, but may be arranged upon any other portion of the vehicle.

The improved device comprises an outer casing or shell formed with a bottom 11, ends 12 and 13, back 14 and front. 15, and an inner portion of non-conductive material such as cork or other non-heat conductive material, and formed with bottom portion 16, end portionsl'? and 18, back 19 and in section on the line front 20. The inner non-conductive mem-- offset. laterally as shown at 27, and bear thereby. upon the upper edges of the o'uter and inner. portions, and thus form closures to the air spaces. I

J Air vent openings 28 are formed through the end portions 12 and 13 of the outer portion or shell, and a drainage tube 29 leads from theinner or food chamber within the sheet metal body portion 33 is a layer of forms a part of the non-conductive material of cork or the like represented at 35. c The closure device is preferably hinged to the rear outer member 14 as shown at 36. Supporting straps37 are attached to the bottom 11 and formed with depending hooks 38 at the ends to bear over the edges of the support, for instance the running board or other portion of the vehicle, to prevent lateral displacement, and other strapdevices, indicated at 39, will be employed, to lock the device to the support and prevent its vertical displacement.

The improved device is simple in construction, can be made of any size or capacity and of any suitable material, either wood or metal, or partly of wood and partly of metal, as may be preferred. The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification but it will be understood that modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention what is claimed is:

1. A refrigerator device comprising an outer shell'open at the top, an inner shell of nonconductive material open at the top and spaced from the outer shell, a sheet metal lining for'the inner shellwith its upper portion outstanding and extended over theouter shell and constitutinga closure for the space between the shells, a closure for the inner shell formed of a sheet metal body having upstanding outer portions to engage Within said lining member and outstanding portions extending from the upstanding portions of the body and bearing upon the outstanding portions of the lining, an outer cover member bearing upon the outstandin portions of the lining, and a member or nonconductive material bearing upon the.

sheet metal body and spaced from the outer cover member.

2. A refrigerator device comprising an outer shell open at the top, an inner shell of noneonductire material open at the top and spaced from the outer shell, a sheet metal lining for the innershell with its upper portion outstanding and extended over the outer shell and constituting a closure for the space between the shells, vent openings through two opposite walls of the outer shell, a closure for the inner shell formed of a sheet metal body having upstanding outer portionsto engage Within said lining member and outstanding portions extending from the upstanding portions of the body and bearing" upon the outstanding portions of the lining, and a member of noncondnetive material bearing upon the sheet metal body and spaced from the outer cover memher.

In testimony whereof, I affix my signa ture hereto.

FRED D. PRATT.
